A's McCarthy completely different pitcher than he was with Sox

'Now I'm attacking in different ways'

The White Sox might not face Brandon McCarthy until they travel to Oakland next month, but they'll see a different pitcher than the one who helped them win a 2005 World Series title.

McCarthy, who beat the Twins on Sunday, said he's a more complete pitcher than he was with the Sox, when he loved to throw his changeup almost exclusively. He also has altered his delivery.

"It's nice I'm able to do a lot more against lineups than I did in the past," said McCarthy who coped with injuries with the Rangers from 2007-09. "Before I was one-dimensional, and if you took a pitch away from me, I was in trouble. Now I'm attacking in different ways. I can change things and go through lineups with a little more effectiveness and pitch efficiency and not work as hard."

McCarthy, 27, beat a predominately left-handed-hitting Twins lineup and has pitched at least 7 1/3 innings in each of his two starts.

"There is nothing the same from when I was here," McCarthy said. "It's sinker, cutter, changeup, curveball. I try to move every fastball I throw. I want early contact. It's a completely different game now."

Delay on Dunn: Manager Ozzie Guillen intimated that Adam Dunn might not return until Friday, less than a week since undergoing an appendectomy. Dunn has experienced discomfort while running the bases.

"When he tells me he's ready to go, I am going to give him an extra day," Guillen said.

Walker's endorsement: After being named the American League co-player of the week for the period ending Sunday, Paul Konerko spoke highly of hitting coach Greg Walker.

"He's my guy when it comes to hitting," said Konerko, who shared the honor with Indians shortstop Asdrubal Cabrera. "He and (assistant hitting coach) Mike Gellinger, they are two of the smartest hitting guys I've been around. We are lucky to have them and I use them as much as I possibly can on all things hitting."
